Product Overview

The Track Roller, also known as Bottom Roller or Lower Roller, is a key undercarriage component installed beneath the track frame of crawler bulldozers.

The compatible track roller for Komatsu D60 and Shantui SD16 supports the machine operating weight, guides the track chain and helps maintain proper crawler alignment during travelling, grading and earthmoving operations.

During bulldozer operation, track rollers are continuously exposed to:

• Heavy machine loading
• Impact from uneven terrain
• Rock and gravel abrasion
• Mud, dust and water
• Continuous travelling and pushing loads

A worn or damaged track roller may cause:

• Track chain misalignment
• Excessive travelling vibration
• Abnormal track noise
• Uneven track wear
• Accelerated sprocket and track link wear
• Increased maintenance costs and machine downtime

Our D60 / SD16 track rollers are manufactured using professional undercarriage production processes to provide a reliable aftermarket replacement solution for construction, earthmoving and heavy-duty bulldozer applications.
